ABSTRACT:
Problems with prior OSI (Open Systems Interconnected) event forwarding discriminators (EFD) are solved in accordance with this invention by creating a new type of EFD, called a notification forwarding discriminator (NFD). An NFD works just like an EFD in that it receives notifications emitted by managed objects and determines what types of notifications should be forwarded. However, the forwarding mechanism in an NFD is completely different. An NFD has two operations that a management application can use to control subscription to notifications, "start" and "stop". An NFD forwards notifications via responses to a solicited "start" operation without signaling the end of the "start" operation. Hence, a "start" operation will always be pending completion. The manager and agent track this pending status of operations between a manager and an NFD. Both the manager and agent maintain a pending completion list for each link between a manager and agent. There is a one-to-one correspondence between each manager and the link over which requests go to a given NFD through an agent. Multiple applications using the manager may send multiple start operation requests through the manager, through the agent and to the NFD.
